Interpretive Summary:

Technical Abstract: Several new diseases have been described and the causal agents characterized in the past few years. Green mosaic remains an elusive disease with unknown distribution. Symptoms resemble that of the well-characterized mosaic disease but in this case foliar symptoms show a light green color in contrast to its counterpart where symptoms vary greatly in color for yellow to orange to red to green and purple. A virus was detected in all symptomatic plants collected in New Jersey and fully characterized. It belongs to the genus Vitivirus, members of which are transmitted mechanically, by mealybugs or aphids. The presence of the virus in other major production areas across the United States and British Columbia, Canada was investigated. Green mosaic associated virus was found in very low numbers in the Southeast, Northeast and Midwest, indicating that it does not pose a major issue for the industry at this point.
